Front

What are the main parts of a neuron?

Back

The main parts of a neuron are the dendrites, cell body (soma), and axon.

Front

What is the function of dendrites?

Back

Dendrites receive signals from other neurons and transmit them to the cell body.

Front

What is the role of the cell body in a neuron?

Back

The cell body contains the nucleus and organelles, and it integrates incoming signals.

Front

What is an axon?

Back

An axon is a long, slender projection of a neuron that conducts electrical impulses away from the cell body.

Front

What is a synapse?

Back

A synapse is the junction between two neurons where communication occurs through neurotransmitters.

Front

What is the difference between the central nervous system (CNS) and the peripheral nervous system (PNS)?

Back

The CNS consists of the brain and spinal cord, while the PNS includes all other neural elements.

Front

What is the somatic nervous system?

Back

The somatic nervous system controls voluntary movements and transmits sensory information to the CNS.

Front

What is the autonomic nervous system?

Back

The autonomic nervous system regulates involuntary bodily functions, such as heart rate and digestion.

Front

What are interneurons?

Back

Interneurons are neurons that connect sensory and motor neurons and process information within the CNS.
